I would like to say 'At my local store' but they are as rare as hen's teeth around here. I don't like to buy things unseen so I tend to have a look at equipment that I have in mind when I'm about elsewhere before I make my mind up. I have answered 'Via mail order from an advert'. That way a local independant store (albeit not local to me) will get my business. I've used several from the back of AP and had good service every time.
